What is ExerciseDiary?

Exercise Diary is a self-hosted workout tracking application that visualizes your exercise history in a GitHub-style contribution heatmap. It supports logging workouts with categories, tracking body weight over time with charts, and viewing statistics. The web interface offers multiple Bootswatch themes and a configurable light/dark color mode. Authentication is optional via session cookies with bcrypt password hashing. It runs as a single Go binary, available as a Docker image (aceberg/exercisediary) or downloadable binaries (including a .deb package via PPA). Configuration uses environment variables or a config.yaml file. The project is pre-1.0 (version 0.1.9) with a roadmap showing core features complete and PostgreSQL support planned.
